BOOKS WANTED. _So many of our Correspondents seem disposed to avail
themselves of our plan of placing the booksellers in direct
communication with them, that we find ourselves compelled to limit each
list of books to two insertions. We would also express a hope that those
gentlemen who may at once succeed in obtaining any desired volumes will
be good enough to notify the same to us, in order that such books may
not unnecessarily appear in such list even a second time._
P. G. _We are not in a position to answer_ P. G.'s_inquiries. Why not
try one of the series and judge for yourself?_
A GERMAN INVESTIGATOR, _who states that some important moves towards the
"flying by man" have lately been made upon the Continent, and who
inquires "what noblemen or gentlemen would be likely to foster similar
researches in this country," should rather address himself to some of
the journals devoted to mechanical science._
SCIOLUS. _The author of_ Doctor Syntax _was the well-known_ William
Coombe, _a curious list of whose works will be found in the_ Gentleman's
Magazine _for May, 1852, p. 467._
CHARLES DEMAYNE. _We have a letter for this Correspondent; where shall
it be sent?_
ERICA _will find his illustration of Campbell's_ Like Angel Visits
_anticipated in our_ 1st Vol.
J. N. C. (King's Lynn). _We have one or two Replies on the same subject
already in the Printer's hands._
A. J. V. (University Club) _will find his Query respecting_ Solamen
miseris, &c. _in_ Vol. viii., p. 272., _and an answer respecting_
Tempora mutantur _in_ p. 306.
_Our Correspondent_ C. E. F. (p. 373.) _is informed_--1. _That both the
solutions of the muriate salts and the nitrate of silver may be used in
the manner he proposes; but a portion of sugar of milk, mannite, or
grape sugar, as has been previously recommended, much accelerates the
process._ 2. _The positives should be printed about one-third deeper
than is required, and they should remain in the hypo. bath until the
mottled appearance is removed, which is visible when held up against the
light and they are looked through: at first the positive often assumes a
very unpleasant red colour; this gradually disappears by longer
immersion, when the proofs may be removed at the point of tint required,
remembering that they become rather darker when dry, especially if
ironed, and which is generally desirable, especially if the print is
rather pale._ 3. _The sel d'or does not seem to have the destructive
effect which the chloride of gold has, and if the chemicals are entirely
removed, in all probability they are quite permanent. Those which we
have seen printed several months since appear to have suffered no
change. Pictures produced by the ammonio-nitrate are most uncertain.
There are few who have not had the mortification to see some of their
best productions fade and disappear. A learned professor, about eighteen
months since, sent us a picture so printed "as something to work up to;"
a few yellowish stains are now all that remains on the paper._
